Hi, I know only people who have problems post here and we don't hear from satisfied users, but the 4850 freezing issue seem to be quite systematic. Would you all say the Apple update has fixed that? From past history, one poster said an update typically fixes something like 90% of the issues then another update 6 or so months later fixes the remaining 10%. Is that the case with the current 4850s? Also heard about bluetooth problems connecting with the wireless mouse and keyboard. I'd simply upgrade to the Mac Pro with the 4870, but I've read they are, although much less, having issues too. I think the issue is regarding drivers too. In terms of which computer is right for me, I'd say the power of the iMac 4850 is appropriate, and the MP a bit overkill, but I would grow into it over the years. Hmm, I wonder if it's better to keep a MP long term or buy iMac's more frequently??
